    Product strategy consultant

    A product strategy consultant works out which customer problem your company will win at, why you can win it, and what sequence of work gets you there — then turns that into a roadmap and an operating model the team can run without them. Good product strategy is mostly subtraction: naming the things you will deliberately not do, so the things you will do get enough resource to matter.

    WHO THIS IS FOR

    Signs your product strategy is not real yet

    • Your roadmap is a list of features with no explanation of what each one is meant to change.
    • Two people in your leadership team would describe the target customer differently.
    • Everything is a priority, which in practice means the loudest customer sets the sprint.
    • You ship consistently and the core metrics do not move.
    • You cannot say what you have decided not to build this year.
    • Your positioning is a category label — 'AI platform for X' — rather than a problem you solve better than anyone.

    WHAT THE WORK COVERS

    Strategy across the seven stages

    Strategy is not a stage of its own; it is the thing that makes each stage decidable. Here is what it looks like practically at each point in the journey.

    Discover & Validate

    Choosing which customer segment and which problem to serve, and defining the evidence that would make you abandon that choice. A strategy with no falsifying condition is a slogan.

    Prototype & Build

    Sequencing. Which capability has to exist first for the rest to be worth anything, and what the smallest credible version of it looks like.

    Launch & First Revenue

    Positioning, packaging and pricing as strategic choices rather than marketing afterthoughts. Who you charge and how much is a statement about who you are for.

    Scale

    The operating model: how decisions get made, what gets measured, what the planning cadence is, and how the strategy stays visible when the team doubles.

    HOW IT RUNS

    The strategy sprint

    1. Days 1-3

      Evidence gathering

      Customer interviews, sales call recordings, churn reasons, usage data, competitor teardown and interviews with your own team. Strategy built on internal opinion alone is expensive fiction.

    2. Days 4-5

      Diagnosis

      A written statement of the actual problem the business faces. Usually not the one that prompted the engagement — the presenting complaint and the underlying issue are rarely the same.

    3. Week 2, days 1-2

      Strategic choice

      Segment, problem, differentiator and the explicit list of what the company will stop doing. Presented as options with trade-offs, decided together, not handed down.

    4. Week 2, days 3-4

      Roadmap

      Twelve months, three horizons, each item tied to the outcome it is supposed to move and the evidence that would prove it worked.

    5. Week 2, day 5

      Operating model and handover

      Planning cadence, decision rights, the metric set, and a one-page strategy document the team can hold in their heads.

    PRICING

    Strategy pricing

    Strategy work is priced as fixed-scope engagements. You get the artefacts regardless of how long they take me.

    Product audit

    £2,500

    One week. Written diagnostic on strategy, roadmap quality, discovery practice and metrics, with a prioritised list of what to fix first.

    Strategy sprint

    £4,000-£6,000

    Two weeks. Evidence gathering, diagnosis, strategic choice, twelve-month roadmap and operating model. The most common engagement.

    Embedded strategy

    £4,000-£10,000/mo

    Ongoing as a fractional CPO — strategy plus the accountability for making it happen quarter after quarter.

    COMPARISON

    Independent consultant vs a strategy consultancy

    Big consultancies do genuinely useful work at scale. At seed and Series A, the economics and the failure modes are different.

    PROOF

    Strategy applied, not theorised

    Wocal: from one venue to 300+

    The strategic decision that mattered was narrowing from 'hospitality software' to one specific job for one specific venue type. That subtraction is what produced the growth and the £2.7M pre-money valuation between 2020 and 2025.

    Just Eat, 2021-2025

    Four years seeing how strategy behaves at marketplace scale — where the constraint is rarely ideas and almost always alignment across commercial, operations and product.

    Sage

    Enterprise SaaS, where product strategy has to survive contact with procurement cycles, existing contracts and a customer base that did not ask to be modernised.

    Echo-U

    Contact-centre operations. The clearest education available in the true cost of a product decision, because every unclear interface arrives as a support call with a name attached.

    Most product strategy documents are not strategies

    A strategy is a diagnosis, a guiding choice, and a coherent set of actions that follow from it. Most documents labelled product strategy contain none of these. They contain an ambition — 'become the leading platform for X' — a set of themes, and a roadmap. Ambition is not diagnosis. Themes are not choices.

    The test is simple: does the document say what the company will not do? If the strategy is compatible with every plausible course of action, it cannot guide any decision, and it will be ignored by everyone below the leadership team within a month.

    The second test: is there a falsifying condition? A real strategic bet can be wrong. If you cannot describe the evidence that would make you change course, you have not made a bet — you have described a hope.

    The diagnosis is the hard part

    Almost every strategy engagement begins with the wrong problem statement. The founder says growth has stalled and the roadmap needs sharpening. Three days of evidence gathering reveals that activation is fine, retention is fine, and the actual issue is that the highest-value segment churns at renewal because a competitor solved an adjacent problem they consider part of the same job.

    Getting to that requires talking to people outside the building. Customer interviews, yes, but also lost-deal conversations, churned-customer conversations and the sales calls where the prospect politely disengaged. Internal opinion is systematically biased toward the problems the team already knows how to solve.

    Once the diagnosis is right, the strategic choice is usually obvious and frequently uncomfortable, because it involves stopping work that people are emotionally invested in. That is why the diagnosis has to be evidenced rather than asserted — the evidence is what makes the stopping possible.

    Turning strategy into a roadmap that survives

    • Every roadmap item names the outcome it is meant to move, not just the thing being built.
    • Three horizons: committed for the current quarter, likely for the next two, directional beyond. Precision beyond six months is theatre.
    • Each item carries the evidence that would prove it worked, agreed before the build starts.
    • An explicit 'not doing' list, published, with the reasoning. This is what makes the roadmap defensible when a big customer asks.
    • One page. If the strategy does not fit on a page, the team will not carry it in their heads, and a strategy nobody remembers is not operating.

    The operating model is where strategy usually dies

    A good strategy with a bad operating model produces a company that agrees on direction and drifts anyway. The operating model is the boring machinery: who decides what without escalating, what the planning cadence is, which metrics get reviewed weekly versus quarterly, and how discovery work gets funded when delivery pressure is high.

    The most common failure is that discovery has no protected time. Everyone agrees that talking to customers matters, nobody has it in their calendar, and within two quarters the roadmap is being built from internal guesses again. The fix is structural, not motivational: a fixed number of customer conversations per person per month, reviewed like any other commitment.

    The second most common failure is unclear decision rights. When nobody knows whether a PM can change scope without the founder, everything escalates, the founder becomes the bottleneck, and the strategy stops guiding anything because every decision is made ad hoc in the moment.

    FREQUENTLY ASKED

    Product strategy consulting questions

    What does a product strategy consultant do?
    A product strategy consultant diagnoses why a product is not achieving what the business needs, chooses which customer and problem to focus on, and converts that into a roadmap and operating model the team can run. The output is a small set of decisions with reasoning attached, not a large deck.
    How much does product strategy consulting cost?
    A one-week product audit is around £2,500. A two-week strategy sprint producing diagnosis, strategic choice, a twelve-month roadmap and an operating model runs £4,000 to £6,000. Ongoing embedded strategy work as a fractional CPO is £4,000 to £10,000 per month.
    How long does a product strategy engagement take?
    Two weeks for a full strategy sprint. That is enough time for evidence gathering, diagnosis and decisions, and short enough that the work does not drift. Longer engagements tend to produce more documentation rather than better decisions.
    What is the difference between product strategy and a roadmap?
    Strategy is the choice of which customer problem you will win and why you can. The roadmap is the sequence of work that follows from that choice. A roadmap without a strategy behind it is a list of features ordered by whoever asked most recently.
    Do you work with pre-product-market-fit companies?
    Yes, and the work looks different. Before product-market fit the strategy question is which segment and problem to bet on and how to test it cheaply. After it, the question is how to defend and expand a position you have already found.
    Will you implement the strategy or just write it?
    Either. Many companies take the strategy sprint output and run it themselves. Others continue with me as a fractional CPO at one to three days a week, which means the same person who set the direction is accountable for it quarter after quarter.
    How do you handle disagreement in the leadership team?
    Surface it early with evidence rather than debate. Most leadership disagreement about product is actually disagreement about which customer matters most, and that resolves quickly once you look at real retention and revenue data by segment.
    What do I get at the end?
    A one-page product strategy, a written diagnosis, a twelve-month roadmap across three horizons with outcomes attached, an explicit list of what the company will stop doing, a defined metric set, and an operating cadence documented well enough for your team to run it without me.
